AEROPLANE WITH V-SHAPED WINGS Filed June 22, 1931 J l6 7' if? f 16 Igwuewioz N% W/izEBeZZ Patented Feb. 21, 1933 PATENT OFFICE WILLIAMERNEST BELL, F CHARLOTTE, NORTH CAROLINA AEROPLANE WITH 'V-SI-IAIPEDWINGS Application filed June 22, 1931.

The object of my invention is to provide an aeroplane having a novelwing construction adapted to increase the speed of the aeroplane and toincrease its lateral stability and its lifting power. It is also anobject of my invention to apply my improvements to planes having eitherthe usual cockpit or to a cabin plane.

I obtain the objects of my invention by the means illustrated in theaccompanying drawing, in which,

Figure 1 is a top plan view of my invention;

Fig. 2 is a side elevation of same;

Fig. 3 is a section through one of the wings on the line 33 of Fig. 1,showing the curvature of the wing in cross section; and

Fig. 4L is a rear elevation of the wings and detached from the body ofthe areoplane.

Like numerals designate like parts in each of the several views.

Referring to the accompanying drawing, there is illustrated an aeroplanehaving a conventional fuselage 1 and cockpit 2. I provide novel V-shapedwings 3 fastened to the fuselage at the central portions 8 and alsosecured to same by the central brace 9 which is fastened to the body ofthe aeroplane back of the cockpit as shown in Fig. 1; also braced by thelateral braces or straps which are fastened to the underside of thewings and to the sides of the fuselage as illustrated in Fig. 3. Thewings 3 are suitably affixed or attached to the fuselage or to eachother as by members 5. It will be especially noted that the nose or apex4 of the aeroplane wings may, if desired, extend over and be positionedforward of the aeroplane propeller 13, and that the wings terminate insubstantially pointed ends 16 as shown in Figs. 1 and 2. The wingsextend rearwardly at an angle of approximately 50 degrees to each other,as shown in the drawing, and slant upwardly from the fuselage at anangle of between 8 to 10 degrees from a plane drawn horizontally throughthe point of connection through the wings and the fuselage as shown alsoin the drawing.

The wings are preferably provided with 50 suitable shatterproof glasswindows 6 to en- Serial No. 546,082.

able the pilot to have a clear view through the wings in the case ofaeroplanes of the cockpit type. In the cabin type of plane such windowsare unnecessary.

I provide a suitable or conventional horizontal rudder 10 having movablerudder sections or vanes 11, and a conventional vertical rudder 12. Therudders 11 and 12 and ailerons? are operated by any suitableconventional means, not shown in the accompanying drawing and notclaimed as a part of this invention.

When the aeroplane is in operation the V-shaped or three-pointed wings 3have a V tendency to increase the speed of the plane, to improve itslateral stability andto increase its lifting power. The wings are somounted that the plane is evenly balanced and the Wings form a trueV-shape. A novel and advantageous feature of the invention is the 7Gdisposition of the forward portion of the wings over the propeller 13. Agreater lifting power and a more even balancev of the plane is obtainedthereby. The V-shaped wings have a tendency to reduce a great deal ofwind resistance, and thereby to increase the speed of the plane.

The invention may also be applied to cabin planes and-when applied tocabin planes it is not necessary to provide the glass windows 6 in thewings.

What I claim is:

In combination with an aeroplane, substantially V-shaped wings disposedat an angle of approximately 50 degrees to each other, said wingsterminating in substantially pointed ends, said ends being disposed inthe same plane as the main body of the wings and the wings beingdisposed in an upwardly slanting direction of between approximately 8 to10 degrees from the point where they are attached to the fuselage toincrease lateral stability.
